Official Alpine/musl compatible Docker image for v4.8.0 #1293

Hi, thanks for the v4.8.0 release.

Currently, the official pre-built binaries target glibc-based systems
(Linux x86_64-gnu, Windows, macOS), but there is no official Docker
image built for Alpine Linux / musl libc.

Many NAS platforms (e.g. Synology Container Manager) and lightweight
server environments rely on musl-based images, and the existing
community images (e.g. angelics/unraid-docker-ravencoin-p2p) are still
on older versions like v4.6.1, which lacks the fixes introduced in
v4.7.0/v4.8.0 (nHeight validation, asset overflow fix).

Would it be possible to publish an official Alpine/musl compatible
build (or Docker image) for v4.8.0? This would help node operators
running on musl-based systems stay on a secure, up-to-date version.

Thanks for your work on Ravencoin!
